For the first time, NASCAR fans will get to determine several key aspects of how the preseason exhibition race -- which features pole winners from last season -- is run. The changes have not been formally announced, but they were viewable on NASCAR's new mobile app and on NASCAR's websiteon Sunday morning.

Fans will vote on the race format (how the segments will be broken up), a required pit stop, how many cars will be eliminated and what the design of Miss Sprint Cup's firesuit will look like.

Votes cast in the app will be counted double. Here's a rundown of the categories:

Race Format: How should the three race segments be divided?

-- 40/20/15 laps

-- 35/30/10 laps

-- 30/25/20 laps

Pit Stop: Should there be a required pit stop at the end of the first segment?

-- No pit stop

-- Yes, two tires

-- Yes, four tires

Elimination: How many cars should be eliminated at the end of the second segment?

-- None

-- Two cars

-- Four cars

-- Six cars

Voting for the race format ends Feb. 13; all other categories will close Feb. 16.

In addition, fans are being asked to vote on which yellow firesuit Miss Sprint Cup will wear for the race.
